Not sure on the SK setup... I believe if you are running the newest firmware from SK there is an issue... I had a Beta Tester using SK and it was working great and then they upgraded firmware on the SK and it no longer worked... Maybe one of the SK will chime in... Thanks.

I tried the new firmware with a SK540 and my Futaba 8FGH with Sbus receiver and had no problems. I set the end points to 100,100 and set the hold value to 15%. Plug in the ESC with the hold switch on and it arms every time. I made a few test flights and it does ok with those settings. I did not attempt to setup the Auto bailout but I have heard from others that Skookum needs a firmware update to make that reliable.

Skookum is going to have improved firmware out soon with improved governor for EP.

The main problem is that the SK's (540, 720) does not pass though a throttle signal below idle throttle point, calibrated in Skookum setup software. You need to set the SK's idle thottle to esc arm point, not to hold point as setup program advises. Currently it is the only one solution (as I know), as long as Skookum is not make changes in firmware. If they're going to do it...
Sorry for my English.

I was able to get low end throttle end point set through the Sk software but not the high end this morning. The crazy thing is, the esc armed at end point 140 which on 8j the max. Now. My throttle channel in the transmitter is reversed, it always has been and b4 the latest software update I was running the throttle through the SK but using the CC governor. Could the throttle be reversed in the SK? I'll go through it again a little later. It seems to be working fine in airplane mode, sans auto bailout but I'd like it to be set up correctly.

My problem is in setting the end points. I cant get any response from the esc if I attempt to set them with the throttle lead through the SK540( I dont have this problem when setting up the throttle normally, without governor turned on.) and if I attempt to set the end points out side of the SK first through the reciever it works unttil I unplug the esc then plug it back in, then the esc will not arm. I got it to work with the esc in airplane mode but its glitchy and it does"t feel like the rpm is correct. So its back to the CC governor for now.

regarding not being able to clear data log by arming esc with full throttle. I noticed this too and assumed it might be fixed when the firmware was released. Anyone know if external governor mode disables it?

This is actually a SK glitch that will be fixed with the next firmware. There is a way around it described here http://www.rchelination.com/sk540-governor-with-cc-esc/ The performance on the SK Gov is quite worth it over the CC gov. The update will allow use of either the SK softstart and bailout or the CC soft start and bailout btw
